Dress for a Cocktail Event

I am having a hard time finding the perfect cocktail dress for year end’s party. I need a new cocktail dress, something suitable for a semi-formal occasion, preferably black, not too flashy, above-the-knee length, plus size dress and most importantly, something not expensive! Help! I don’t want to buy from malls since they really cost a lot besides, I’m quite busy these days and it’s not really easy to find my size. 2 years ago, me and some friends tried to get made-to-order gowns from Divisoria but failed at it. The gowns weren’t done on time, looks like he really rushed doing them, they turned out ugly! Another option is to order online, quite easy and there are a lot of gowns to choose from, only problem is that I might end up paying thousands for the shipping alone. Haaay, if you know some good designers within QC you can refer, PM me pls. Thanks!
